HEADLIGHT.

Application filed April 6,

To all whom it may concern:

Be it known that I, ABRAM A. BOLLINGER, a citizen of the United States, residing at Gastonia, in the county of Gaston and State of North Carolina, have invented a new and useful Headlight, of which the following is a specification.

This invention aims to provide a simple means whereby when a locomotive engine moves along a curved track, the headlight on the engine will be caused to throw its rays along the track and follow the curve, thereby illuminating the curved portion of the track.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

I have selected for illustration, one form which my invention may take, but it is to be understood that a mechanic, working within the scope of what is claimed, may make such changes as his skill may dictate, without departing from the spirit of the invention.

The invention will be understood best when the following description is read in connection with the accompanying drawings and in the said drawings, Figure 1 is an elevation, showing a portion of a locomotive engine wherewith the device forming the subject matter of this application has been assembled; Figure 2 is a section on the line 2-2 of Figure 1; and Figure 3 is a section on the line 33 of Figure 2.

The numeral 1 marks a locomotive engine having wheels 2 adapted to roll on the rails 3 of a track, the pilot 5 being carried by a part 4 of the engine frame. A base plate 6 is attached by securing elements 7 to the under side of the frame 4 and is supplied at its forward end with depending brackets 8 abutting against the pilot 5. A first shaft 9 is journaled in the plate 6, in the frame 4 and in a bearing 10 which may be mounted on the smoke box of the engine 1, a lamp 11 being secured to the upper end of the shaft. The lamp 11 may be located as desired, in accordance with common railroad practice. A pinion 12 is secured to the lower end of the shaft 9 below the plate 6 and meshes with a segment 17 on an arm 16 projecting from the intermediate portion of a cross head 14 mounted pivotally at 15 on'the base 1923. Serial No. 630,318.

plate 6 to swing thereon. The cross head 14 is provided at its ends with depending feet 18 carrying shoes 19 adapted to cooperate with the inner edges of the rails 3. Retractile springs 20 are secured at their forward endsto the brackets 8 and are secured at their rear ends to the cross head 14. The springs 20 serve to hold the cross head 14 yieldingly at right angles with the line of advance when the locomotive 1 is moving along a tangent. The segment 17 and the pinion 19 constitute a reversing gear connection between the cross head 14 and the lamp shaft 9.

When the locomotivel passes from a tangent to a curve, one of the shoes 19, cooperating with the corresponding rail 3, causes the cross head 14 to swing on its pivotal mounting 15, rotation being imparted to the shaft 9 by way of the segment 17 and the pinion 12, the lamp 11 being swung later- T ally, so that the light proceeding from the lamp will follow the curve which the train is travelling.

What is claimed is In a device of the class described, a base plate adapted for mounting on the under side of the pilot-frame of a locomotive engine, and provided at its forward end with a depending portion, a shaft journaled in the base plate and of sufficient height to extend above a pilot-frame, a lamp on the upper end of the shaft, a pinion on the lower end of the shaft and located below the base plate, a cross head mounted intermediate its ends on the base plate and lo- ABRAM A. BOLLINGER.
